摘要： In an optical fiber device having a configuration in which an optical fiber is joined to a side surface of another optical fiber, a joint portion is suppressed from reaching a high temperature. The optical fiber device includes a first fluoride fiber, a second fluoride fiber, and a heat dissipation member. The first fluoride fiber guides light. The second fluoride fiber has a first end on or from which light is incident or output and a second end at which an end surface of the second fluoride fiber is obliquely joined to a side surface of the first fluoride fiber.
